Validation of the Chinese version of the Scale for Suicide Ideation-Worst in adult patients with epilepsy.

OBJECTIVE: The aim of this study was to validate the Chinese version of the Scale for Suicide Ideation-Worst (SSI-W) for screening suicide ideation in Chinese adult patients with epilepsy (PWE). METHOD: A consecutive sample of Chinese adult PWE from a tertiary hospital completed the SSI-W and the suicidality module of the Chinese version of the Mini International Neuropsychiatric Interview (MINI) Plus 5.0.0. RESULTS: A total of 269 PWE completed the scales. According to the MINI, 59 patients (21.9%) had suicidal ideation. The Cronbach's α coefficient for the SSI-W was 0.96. Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) for the SSI-W was 0.957 (95% confidence interval [CI] = 0.935-0.980). With a cutoff score of 2 points, the SSI-W demonstrated the best psychometric properties: a sensitivity of 95.8%, a specificity of 87.3%, a positive predictive value (PPV) of 56.7%, and a negative predictive value (NPV) of 99.0%. The scores for items 11 (Reason for attempt) and 18 (Final acts) were not significantly different (p > 0.05) in patients with suicidal ideation, while the scores for the other items were significantly different between these groups of patients. CONCLUSION: The Chinese version of the SSI-W proved to be a reliable and effective assessment tool for screening suicidal ideation in Chinese adult PWE.

Validation of the Chinese version of the Hamilton Rating Scale for Depression in adults with epilepsy.

OBJECTIVE: This study aimed to validate the Chinese version of the 17-item Hamilton Rating Scale for Depression (C-HRSD-17) for use in adult patients with epilepsy (PWE). METHODS: A consecutive sample of Chinese adult PWE from a tertiary hospital was examined using the C-HRSD-17 and the Mini International Neuropsychiatric Interview (MINI) Plus Chinese Version 5.0.0. RESULTS: A total of 191 PWE completed the assessment of depression. According to the MINI, thirty patients (15.7%) had current major depressive disorder (MDD). The Cronbach's α coefficient for the C-HRSD-17 was 0.832. Receiver operating characteristic (ROC) analysis showed an area under the curve (AUC) of 0.983 (95% CI = 0.968-0.998). With a cutoff score of 9, the C-HRSD-17 demonstrated the best psychometric properties, with a sensitivity of 96.7%, a specificity of 93.8%, a positive predictive value (PPV) of 74.4%, and a negative predictive value (NPV) of 99.3%. CONCLUSION: The C-HRSD-17 proved to be a valid and reliable assessment tool, with a cutoff score of 9 for screening of current MDD in Chinese adult PWE.
